revision 1.1 page 11 of 22 nrfgo starter kit user guide the s9 switch ( 2) in figure 2. ) is the main power switch. you can turn on and off the power for the nrfgo motherboard using this switch. using switch s8 ( 2! in figure 2. ) you can select if the power supply is sourced from vbus in the usb connector ( 1( in figure 2. ) or if it should supply the external power sup- ply connector j3 ( 2@ in figure 2. ). the 3xaaa battery pack supplies the board if neither exte rnal power supply opti ons are pres ent. when using batteries the s9 switch is still the main power switch, bu t setting the s8 switch is no longer relevant. the regulated supplies on the nrfgo motherboard can supply a total of 500 ma. when external applica- tion circuitry is connected, ensure that the current drain does not exceed this limit. if usb is used as the power supply to the system, ensure that the usb port is capable of delivering 500ma or use an externally powered usb hub. 2.1.2.1 regulated supplies the nrfgo motherboard ha s three separate power nets: vtg, vcc and vext. vtg: vtarget is the power supply for the nrf development kit module. this is a variable power supply, controlled from nrfgo studio pc software following the starter kit. the vtg is split into two branches vtg and vtg_nrf. vtg_nrf is split from vtg and routed through the nrf current measurement header p7 ( e in figure 2. ). on the nrf development kit modules vtg_nrf supplies only the nrf devices. any non nordic semiconductor circuitry is supplied from vtg. this arrangement enables ?nrf device(s) only? cur- rent consumption measurements on p7. vcc: vcc is a fixed 3.8v supply mainly for the nrfgo mo therboard control circuitry. it is available in the nrf module connectors and more importantly in the extension board connectors for development flexibil- ity. vext: vext supplies the signal level shifters and circui try/headers directly interfacing the nrf module. vext on the nrfgo motherbo ard is sourced from the nrf development kit module to ensure correct sig- nal levels interfacing it. in most cases the connector pins vtg and vext are shorted on the nrf module resulting in vext=vtg. please refer to the nrf development kit user guides for details. 2.1.2.2 status leds the nrfgo motherboard has two leds indicating power supply status: ?d9 ( w in figure 2. ) is lit if vcc is present. ?d8 ( q in figure 2. ) is green if vtg is present. 2.1.3 status display the led status display ( r in figure 2. ) shows the id number assigned to the nrfgo motherboard, while it is connected to a pc, by nrfgo studio. the same id will be shown in the nrfgo studio user interfaces. if two or more nrfgo motherboards are connected to one pc, make sure the id number in the user inter- face matches the id on the nrfgo motherboard you want to control.
revision 1.1 page 12 of 22 nr fgo starter kit user guide if you unplug the usb cable linking the motherboard to th e pc, and the board is fitted with batteries, the number assigned to the mo therboard will begin to flash intermittently with a dot (.), this signals that the motherboard?s id may change in nrfgo studio when the motherboard is reconnected to the pc. 2.1.4 nrf reset button the nrf reset button ( o in figure 2. ) is the reset button for the nrfgo development kit module con- nected to moda/modb. pressing this button causes a fu ll reset of the development kit module, but it does not affect the nrfgo motherboard?s main mcu. 2.1.5 ground connection apart from the gnd found in various headers on the nrfgo motherboard a separate gnd connection ( d in figure 2. ) is available for test instruments. 2.1.6 i/o port headers the i/o ports of a nrf development kit module are routed directly to the i/o headers (p8-p11, y in fig- ure 2. ) on the nrfgo motherboard. figure 6. general pinout of the i/o port headers all io header pinouts are identical and shown in figure 6. the number of headers and pins used and the pinout will vary depending on which nr fgo development mo dule is fitted. please re fer to each nrf devel- opment kit user guide for details. 2.1.7 buttons eight buttons ( s in figure 2. ) are provided on the motherboard to offer you a simple way to give device feedback during development. the buttons are connected to the button header (p1, i in figure 2. ). one of the 10-way ribbon or patch cables supplied in the nrfgo starter kit is used to connect the button header (p1) to the wanted device po rt or pin found in the io headers (p8- p11), illustrated in figure 7. 1 2 34 56 78 910 px.0 px.1 px.2 px.3 px.4 px.5 px.6 px.7 gnd vext
